Introduction
The new thermostat range RDG and RDF is very versatile and consists of numerousproducts. The RDG and RDF offer many new features and cover a broad field ofapplications.
This document shall: – give you an overview of the new ranges RDG and RDF– assist you by the selection of the suitable product, and – provide you with helpful information for installation and commissioning
The section “application overview” for each main application – i.e. fan coil unit,universal, heat pumps and VAV – shows what applications are covered by whichthermostat line. The section “product overview” shows the available thermostat variants and theirsupported applications.
Before you startBefore you start selecting a thermostat, we recommend to make the followingpreselection: – Type of main application: fan coil unit, universal, heat pump or VAV– Application: e.g. 2-pipe with electrical heater– Type of control output 1: ON/OFF, PWM, 3-position, or DC 0...10 V– Type of control output 2: ON/OFF, PWM, 3-position, or DC 0…10 V– Type of inputs: e.g. external room temperature sensor, changeover sensor,
key card switch etc.– Type of thermostat: standalone, standalone with 7-day timer, or communicating
thermostat– Thermostat design: wall- or semi flush-mounted– Other important requirements

How to prepare and set upyour room thermostats
Introduction The versatile RDG and RDF thermostats enable you to better satisfy the requirements ofyour customer. This information supports you in setting up your RDG and RDF thermostats.
Control parameters A number of control parameters can be readjusted to optimize control performance andenable additional functions. Because of this, the RDG and RDF can be used in almost anyapplication.
The control parameters are assigned to 2 levels:– “Service” level, and– “Expert” level
The “Service” level contains a small set of parameters to set up the controller for HVACsystems (control sequence) and to adjust the user interface.
The “Expert” level contains control parameters for fan, control inputs/outputs and otherfunctions. Always change the parameters at the “Expert” level carefully, as they impact thecontrol performance and functionality of the thermostat.
In general, after selecting the required application via DIP switch, it is not necessary toadjust the parameters as the unit works correctly with the factory-set parameters.Nevertheless, in some cases, it might be necessary to readjust the application-specificparameters:– Control sequence (P01): select heating/cooling sequence and
changeover function– Multifunctional inputs (P38…P42): select the input functionality for X1, X2 and D1– Control output (P46…P47): select type of output signal (on/off, PWM, 3-pos.)– Fan function (P52...P62): select fan functionality
Installation and set up1. Select a suitable thermostat2. Set application via DIP switch according to the mounting instructions3. Wire and install the thermostat. Apply power 4. If necessary set parameter P01 (control sequence) and other
application-specific parameters
Note: ARG71 – conduit box suitable for RDF semi flush-mount thermostats isavailable as accessory

Application-specific parametersThis parameter is used to set the required heating and/or cooling sequence and to selectautomatic/manual changeover. Depending on selected application parameter P01 will bepreset as follow: – 2-pipe or single-duct application: P01: = 1 = cooling only– 4-pipe application: P01: = 4 = heating and cooling
A sensor of type NTC like QAH11.1 (AI) or a switch (DI) can be connected to the inputterminals. The functionality of the inputs can be freely configured. The factory settings are:
Available function on X1, X2 and D1
– The RDG100 offers two control outputs, each either of type ON/OFF, PWM or 3-position.To select the required type use DIP switch and P46 (1st control output) and/or P47(2nd control output).
– The RDG400 for VAV application offers two control outputs, DC 0…10 V and eitherON/OFF, PWM or 3-position. To select the required type use DIP switch and P46(reheater/cooler control output) and/or P47 (damper actuator, DC 0...10 V or 3-pos.).

RDG and RDF offer an extensive fan control concept with a wide choice of functions andfeatures. The required options can be selected via the control parameters:
– Fan mode automatic – manual/manual only (P03) – Fan active in cooling mode only, active in heating mode only, disable (P52)– Control output for 3-speed/1-speed fan (P53) – Control output for ECM fan, DC 0...10 V signal (P55…P57) on RDG160 – Fan minimum on time (P59)– Operation in dead zone for in conjunction with return air sensor or to avoid damage
due to moisture (P60, P61)– Fan start kick from standstill to overcoming inertia and friction (P58) – Fan overrun to avoid overtemperatures after the electrical heater turned off (P54)– Fan start delay by ON/OFF control to avoid cold or warm air (P67)
Note: For universal application fan operation has to be disabled via control parameter (P52)
On communicating thermostats control parameters can be downloaded viaACS Service Tool.
Note: RDG/RDF requires an external KNX bus power supply if connected via OCI700
After installing and setting up the thermostat, you can check your configuration by goingto the ”Expert” level and select the diagnostic parameters dxx (d01, d02, …).
Communicating, KNX-compatible thermostatsIn connection with Synco 700, the new communicating, KNX-compatible thermostatsoperate in LTE mode. The units are tailored also for use for Synco living or for integrationin BACS via S-mode. For detailed information about installation and commissioning of aKNX system, refer to technical documentation CE1N3127.
Suggestions for energy saving– Use thermostat with 7-day time program – Use thermostat with modulating control outputs (e.g. DC 0...10 V or 3-position)– Use thermostat with ECM fan control (DC 0...10 V)– Use KNX communicating thermostat– Activate auto fan function – Connect external operating mode switchover for central operating mode control– Connect window contacts to avoid energy losses when windows are open – Connect keycard contact for switching the unit to Economy mode when rooms
are not occupied– Define optimum setpoint limitations (heating max. 20 °C, cooling min. 25 °C)
to minimize energy usage– In application with electrical heater, use function “Electrical heater enable” (P38, P40...)– Inform enduser about prolonged absence and present function

FAQ Where are the DIP switches located? On RDG, the DIP switches are located at the rear of the unit.On RDF semi flush-mount units, the DIP switches are located on the innerside of the front panel.
Where do I find the correct DIP switch position?They are shown in the Mounting Instructions and on the product.
How can I set the parameters? The procedure for setting the parameters (“Service” or ”Expert” level) is describedin the basic documentation of the thermostats.
When do I have to set the control parameters?In general, it is not necessary to readjust the parameters since the unit works correctlywith the factory-set parameters. Nevertheless, in some rare cases, you need to readjustthe application-specific parameters during commissioning to enable the desired functions.For that, access the “Expert” level. For detailed information, refer to the technical docu-mentation. The control parameters on the “Service” level for HVAC systems and for adjustingthe user interface can be accessed at any time.
It is possible to reload the default timer setting?Yes. The default timer setting (A1… A8) and the procedure for reloading are describedin the technical documentation.
It is possible to reset the control parameters?Yes. The factory-set control parameters can be reloaded via parameter P71 by changingthe value to “ON” and by confirming with the buttons. For detailed information, referto the technical documentation.
How to check the current settings and the installation?On the “Expert” level, some diagnostic parameters (d01, d02, ….) are available forchecking the selected application, the status of the inputs, and for testing the3-position outputs. For detailed information, refer to the technical documentation.
